UNITED STATES PATENT @Errea VILLIAM P. BRACHMANN, OF NEWARK, NEV JERSEY.

INJECTOR.

SPECIFICATION forming part of Letters Patent No. 347,566, dated August 17, 1886.

Application tiled March 16, 1886. Serial No. 195,506. (Model.)

State of New Jersey, have invented certain new and useful Improvements in Injectors or Ejectors; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, ,which form a part of this specilication.

The object of this invention is to reduce the cost of construction,to facilitate the process of manufacture,and to secure a device of increased simplicity, effectiveness, and convenience.

The invention consists in the construction and combination of parts substantially as will be hereinafter set forth and finally embodied in the clauses of the claims.

Referring to the accompanying drawings,in i

which like letters indicate corresponding parts in each ofthe figures, Figure 1, Sheet 1, is a front elevation of the improved injector or ejector. Fig. 2, Sheet 2, is a side elevation of the same; and Fig. 3, Sheet 3, is a sectional view taken through line In said drawings, A is an outside case cast in resemblance to a-tube or cylinder,and having Vformed longitudinally therein and preferably integral therewith an inner cylinder or cylindrical portion,B,having passages or ways therein, a space being allowed to remain between the inner wall of the outer case and the outer wall of the inner cylinder,as indicated in Fig. 3. The two cylinders provide seats orbearings for several conical tubes or funnel-like plugs,which are threaded to be easily secured to corresponding threads of the said seats. Upon the outside of the outer case, A, is therein a head, F, having passages or ways therein which connect with or are continuations of those of the inner cylinder. Said head F is preferably integral with the. cylinder or tube-like portions A, to obviate the use of joints which are liable to leak, and to secure greater durability and strength. Said head is provided with coupling or attaching bearings,

the one marked g connecting` with awatersupply pipe, and that marked g with a steam-supply pipe connecting with the boiler. Said head F also provides bearing for aspigot, G, which forms with said head a four-way valve, adapted to cut off or allow communication between the interior of the injector and the sources of steam and water.

At the lower end of the case A is formed another projection or head, H. This provides bearings for a one-way val\f'e-spigot,l,and may connect with a pipe to receive the overflow of water.

The two valve-spigots arelinked or coupled together substantially as indicated in Figs. 1 and 2, the valve-spigot G or the handle thereof having a slotted arm, a, on which works an arm, b, of the lower spigot, so that when the handle of the upper spigot -is turned the lower one turns with it and the valves are operated simultaneously by one exertion of the engineer.

The lower portion ofthe tubular outer case, where it connects with or where it carries the lower head, is somewhat contracted in diameter, and into it, just above the said head, is screwed a funnel-like plug, J, the small end of which extends downward. Below said head, into the extremity of the ease, is secured a threaded collar, K, by which the injector is rconnected with the discharge-pipe leading to the boiler. The upper extremity of the case A is closed by a plug, L. The vertical passage in the inner cylinder is enlarged toward its upper extremity, and into the same is screwed, first, a funnel-like plug, D, and then an upper funnel-like or conical plug, C. Between the two plugs is formed a chamber, d, which connects with and receives water from a passage, e, of the four-way valve. Below the funnel-like plug D the smaller portion of the chamber in the inner cylinder connects with a lower passage, f, of the said four-way valve, and below said passage the lower extremity of the Ainner cylinder is provided with the funnel-like plug E. The spigot Gr of the four-way valve is so formed as to close communication between the passages g2 e and gif, and thus cut off the flow of both water and steam, the spigot and its handle then being in IOO the positions shown at I, Fig. 2. It is also adapted by its construction to allow water from the waterway g2 to ilow to the passage e and out through the overllow II, while the steamway y is still closed, and to thus enable the engineer to know that the water is free to ilow into the boiler. Ilhis is accomplished by turning the handle to the position marked 2. The valve II I is simultaneously opened to allow the outllow of this water, so that the engineer can see it. By moving the handle to the position marked 3, the valve II I is closed, and both the steam and water are turned on to ilow freely. The water entering through g2 passes through the passages e into the chamber (l, lwhere it is forced upward by the steam entering from g" through the spigot opening and passage f and plug D. As it is forced upward through the contracted passage c" in the plug C, it strikes the point a on the under side of the plug L, and is turned in its course and caused to descend through the chamber or passage between the walls of the two eylinders, and to fall into the funnel ofthe plug J, where it again comes into contact with live steam, flowing from the passagef through the plug E, and by said steam it is given increased impetus, and passes into the boiler against the Apressure of the steam therein.

By the arrangement of parts above described, should the injector get clogged by sand, &c., the same may be readily cleaned by simply unserewing the cap L and inserting a wire, all the several contracted passages of the plugs ofthe two cylinders being in line,so that said wire has a straight course to the discharge end of the injector.

All the several operations are performed with the one hand-piece, so that the device is more consf'eniently operated and the mode of operation more easily understood.

Having thus described the invention, what I claim as new ism 1. The injector herein described, combining therein the inner and outer cylinders, the cap or plug L, the four-Way valve, and overflowvalve, all said parts bei ng arranged and adapted to operate substantially as and for the purposes set forth.

2. In combination, the ease A., having the inner cylinder, and head F, formed integral therewith, said head having water and steam ways and a spigot therein, the water-way lying above the steamway, and both ways leading to a vertical passage in the inner cylinder, said inner cylinder being open at both ends and the outer cylinder or case being closed at its upper end, and the valves G and H, all substantiall y as and for the purposes set forth.

3. In combination, the ease A, having an inner cylinder, B, and head F connected there- -with, and having the ways cf and chamber d, the plugs C, D, E, and J, all in line, the plug L, to close the end of ease, andthe spigots G and I, all said parts being arranged and adapted to operate substantially as set forth.

4. In an injector, the combination, with the case A, of a four-way-valve, G, adapted and arranged to close the flow of both water and steam to theinjector, to allow the flow of water to the overtlow while the steam is yetcut oil', and to allow the inilow of both steam and water, all substantially as and for the purposes set forth.

5. In an injector, the combination of the inner and outer cylinders, the overflow-valve, and the fourivay valve, the two said Valves being coupled together to work simultaneously, substantially as and for the purposes set forth.

6. In combination, the case A, closed at its upper end and having therein an inner cylinder or tube provided with conical plugs C l) E, and having passages c and f, leading to a four-way valve on the outside of said ease, and said fonr-way valve, all said parts being arranged and adapted to operate substantially as and for the purposes set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 10th day' of March, 1886.
